Article Synopsis
  • The study reviews interactions between antiretrovirals (ARVs) and hormonal contraceptives (HCs), focusing on data from 49 articles that discuss pharmacokinetics (PK) outcomes related to these medications.
  • Findings showed that efavirenz could increase pregnancy rates and affect progestin levels, with some genetic factors exacerbating these interactions; meanwhile, a specific combination of drugs (DMPA with TDF) raised concerns about bone density loss.
  • The authors emphasize the importance of ongoing counseling for patients using efavirenz due to its risks and suggest further long-term research on certain drug interactions to ensure safe contraceptive options.

Introduction: While young women in South Africa may navigate both HIV infection and pregnancy risks, intrauterine contraceptive (IUC) use is low. Though IUCs have low failure rates, concerns exist about whether the IUC is an appropriate method choice for women living with HIV (WLHIV). In this qualitative study, we explore WLHIVs' experiences of using IUC and reasons for discontinuation.

Objective: Digital health technologies have contributed to the adoption of beneficial reproductive, maternal, newborn, and child health (RMNCH) behaviors through social and behavior change programming, including in hard-to-reach settings. On-demand digital health interventions rely on promotions to build awareness and increase use among target audiences. There is little research on preferred content and use of promotional approaches for RMNCH digital health activities.

Afghanistan ranks among the most disadvantaged globally for many key reproductive, maternal, newborn and child health (RMNCH) indicators, despite important gains in the past decade. Youth (15 to 24 years) are a key audience for RMNCH information as they enter adulthood, marry and begin families; however, reaching Afghan youth with health information is challenging. Internally displaced persons (IDPs), including youth, experience additional challenges to obtaining health-related information and services.

Background: Rural Afghan populations have low skilled birth attendance rates and high maternal and infant mortality. Insecurity and armed conflict, geographic barriers, and cultural norms often hinder women's access to facility-based reproductive, maternal, newborn, and child health (RMNCH) services. Community health workers (CHWs) are critical agents for behavioral change in this and similarly fragile settings, where RMNCH information exposure is limited by low literacy and mass media access.

Background: Mobile phone apps for health promotion have expanded in many low- and middle-income countries. Afghanistan, with high maternal and newborn morbidity and mortality rates, a fragile health infrastructure, and high levels of mobile phone ownership, is an ideal setting to examine the utility of such programs. We adapted messages of the Mobile Alliance for Maternal Action (MAMA) program, which was designed to promote healthy behaviors during pregnancy and a newborn's first year of life, to the Afghan context.

Background: Reproductive tract infections (RTIs) are a major cause of morbidity and mortality, yet RTI testing remains limited in resource-constrained settings. We assessed performance of an existing RTI risk assessment screening tool among women living with HIV (WLHIV) considering intrauterine contraceptive (IUC) use.

Methods: We conducted a cross-sectional analysis among WLHIV screened for participation in an IUC trial in Cape Town, South Africa (NCT01721798).

Background: Women living with HIV (WLHIV) have lower rates of contraceptive use than noninfected peers, yet concerns regarding contraceptive efficacy and interaction with antiretroviral therapy (ART) complicate counseling. Hormonal contraceptives may increase genital tract HIV viral load (gVL) and sexual transmission risk to male partners. We compared gVL, plasma VL (pVL), and intrauterine contraceptive (IUC) continuation between the levonorgestrel intrauterine system (LNG-IUS) and copper intrauterine device (C-IUD) in Cape Town, South Africa.

Background: Community health workers (CHWs) in Afghanistan are a critical care extender for primary health services, including reproductive, maternal, neonatal, and child health (RMNCH) care. However, volunteer CHWs face challenges including an ever-expanding number of tasks and insufficient time to conduct them. We piloted a health video library (HVL) intervention, a tablet-based tool to improve health promotion and counseling by CHWs.

Background: Afghanistan has high maternal and infant mortality which is in part driven by high fertility and low modern contraceptive use. Using modern contraceptive methods can reduce maternal and infant mortality, however there are several barriers to modern contraceptive use in Afghanistan. Married men have the potential to hinder or facilitate their wives' contraceptive use.

Malnutrition contributes to direct and indirect causes of maternal mortality, which is particularly high in Afghanistan. Women's nutritional status before, during, and after pregnancy affects their own well-being and mortality risk and their children's health outcomes. Though maternal nutrition interventions have documented positive impact on select child health outcomes, there are limited data regarding the effects of maternal nutrition interventions on maternal health outcomes globally.

Background: Maternal morbidity is common in Bangladesh, where the maternal mortality rate has plateaued over the last 6 years. Maternal undernutrition and micronutrient deficiencies contribute to morbidity, but few interventions have measured maternal outcomes. We compared reported prevalence of antepartum, intrapartum, and postpartum complications among recently delivered women between maternal nutrition intervention and control areas in Bangladesh.

Measurement of cytokines in the lower female genital tract offer insight into risk for HIV infection and reproductive complications. However, few studies have systematically compared mucosal collection methods or whether collection order matters. We compared longitudinal cytokine profiles in matched genital samples collected from women living with HIV using menstrual cup (MC), endocervical swabs (ECS) and swab-enriched cervicovaginal lavage (eCVL).

Background: Women living with HIV (WLHIV) experience high rates of unmet contraceptive need and unintended pregnancy. Contraceptive method-specific continuation rates and associated factors are critical for guiding providers tasked with both reproductive health (RH) and HIV care. We conducted this systematic review to determine whether contraceptive continuation rates differ between WLHIV and uninfected women and, for WLHIV, whether differences are impacted by method type, antiretroviral therapy use or other factors.

Diabetes is a condition where the body is incapable of proper utilization of glucose and one that, if not properly managed, can lead to critical illness. Glucose monitoring and decision support is vital in avoiding potential adverse health effects. Current methods mainly involve invasive blood extraction for the purposes of blood glucose level notification, yet such methods rely on active user participation and subjective interpretation of the result.

Robot-assisted therapy is regarded as an effective and reliable method for the delivery of highly repetitive training that is needed to trigger neuroplasticity following a stroke. However, the lack of fully adaptive assist-as-needed control of the robotic devices and an inadequate immersive virtual environment that can promote active participation during training are obstacles hindering the achievement of better training results with fewer training sessions required. This study thus focuses on these research gaps by combining these 2 key components into a rehabilitation system, with special attention on the rehabilitation of fine hand motion skills.
